We work with both new and existing projects — whether you need a small fix, a highly customized website, a new feature, an eCommerce solution, a third-party integration, or a complete business application built from the ground up. Our main areas of expertise include: WORDPRESS & WOOCOMMERCE • Custom WordPress website development • Highly customized themes and functionality • Elementor development and customization • Custom plugins and integrations • WooCommerce customization • Complex product, pricing and checkout requirements • Performance, security and maintenance • Figma to WordPress development WordPress is one of our strongest areas, especially when a project requires more customization than a standard theme or plugin can provide. SHOPIFY • Custom Shopify theme development • Shopify 2.0 customization • Custom Shopify apps and private apps • Shopify API and webhook integrations • Custom eCommerce functionality • Product, pricing and checkout customizations • Store improvements and performance optimization CUSTOM WEB APPLICATIONS When a project needs something beyond WordPress or Shopify, we build custom applications using modern technologies such as: • React / Next.js • Node.js / NestJS • Laravel / PHP • PostgreSQL / MySQL • REST APIs and third-party integrations • AWS • Git and CI/CD This includes admin panels, dashboards, booking systems, business management platforms, SaaS applications, customer portals, internal tools, and other custom software. DEVOPS & DEPLOYMENT We can also take care of the technical side of getting an application into production — including AWS setup, servers, deployment, Git workflows, CI/CD pipelines, environment configuration, backups, and ongoing maintenance. UI/UX & MOBILE We work with Figma to create and implement clean, responsive interfaces and can also develop mobile applications based on your product requirements. SEO & PERFORMANCE We also help improve website performance and technical SEO, including speed optimization, Core Web Vitals, technical issues, and search-engine-friendly implementation. ⭐ 500+ Five-Star Reviews 🚀 2,000+ Projects Delivered 🌍 Working with businesses worldwide What matters to us is understanding what you actually need before jumping into development. For some projects, WordPress or Shopify is the right solution. For others, a custom application makes more sense. We choose the approach based on the requirements rather than forcing every project into the same technology. Whether you need a quick fix, an existing website or application improved, or a complete system developed from scratch, we're happy to take a look. Send us the requirements, even if they're not fully defined yet. We'll review them and suggest a practical way forward. less
